Mariah Yeater, 20, made headlines last fall when she claimed Bieber was the father of her baby and the singer is only just now laughing about it.

Bieber, 18, tweeted on Saturday, "Dear mariah yeeter…we have never met…so from the heart i just wanted to say…" He then linked to a YouTube clip of Sacha Baron Cohen's Borat character repeating, "You will never get this. You will never get this. La la la la la…"

Yeater withdrew her lawsuit and Bieber's team said in a statement they would, "vigorously pursue all available legal remedies to protect Justin and hold those involved with bring this suit accountable for their actions."

The tweet Bieber addressed to Yeater (though he spelled her name wrong) was part of his "Random Twitter Hour" on Saturday. He tweeted anything and everything that came to mind including, "Kinda weirded out that no one got the secret meaning of #boyfriend Obviously listening closely you can tell its about the migration of birds."
